The Human Body: A Chemical Marvel
The human body itself stands as a testament to the intricate workings of chemistry. The human body is primarily comprised of approximately six essential elements, which include oxygen, hydrogen, nitrogen, carbon, calcium, and phosphorus, making up about 99%. These elements combine to form the complex molecules that constitute our cells, tissues, and organs.
Even our emotions and social interactions have a chemical basis. The chemical known as oxytocin is classified as a type of bonding hormone, which plays a significant role in social interactions and relationships. The digestive system provides another example of chemical processes at work.
The digestive system breaks down foods into simpler forms, such as glucose (sugars), amino acids (components of protein), and fatty acids (components of fats); these nutrients are then likely absorbed into the bloodstream from the small intestine and carried to each cell in the body.
Salt, the primary source of sodium and chloride ions in the human diet, plays an important role in maintaining human health, as sodium is essential for nerve and muscle function and also plays a role in regulating body fluids, blood pressure, and blood volume.
Chemistry and Medicine
Chemistry is mostly important in society because it lies at the core of the development and testing of new medical treatments and medicines for our needs. Chemists likely contribute to the development of modern medicine and drugs, researching molecular combinations and lab procedures that may advance medical products.
Medicinal chemistry focuses on the interaction of natural and synthetic drugs—chemicals used for medicinal purposes—with the complex chemical systems in humans and animals. Medicinal chemistry is concerned with how natural and synthetic drugs, which are chemicals used for medicinal purposes, interact with the complex chemical systems in humans and animals.
The development of new pharmaceuticals, from pain relievers to life-saving antibiotics, relies heavily on chemical research. Even during global health crises, chemistry provides essential tools. Although the full impact is still being explored, chemistry played key roles in understanding COVID-19’s viral structure, as well as in developing chemical preventive measures and drugs to address the pandemic.
Chemistry in Everyday Actions
Chemistry permeates the most mundane aspects of our routines. Everyday instances of chemistry are numerous and diverse, potentially including toothpaste, lotions, facewash, food, pharmaceuticals, batteries in devices like watches, mobile phones, cars, and laptops, as well as the fuel used in vehicles.
From brushing our teeth and preparing food to taking pharmaceuticals and wearing clothes, chemistry appears to play a role in numerous aspects of daily life, potentially including even unexpected areas like the development of solutions for public health crises such as COVID-19. Even the simple act of chopping an onion involves complex chemical reactions. Slicing or dicing an onion releases compounds from its cells into the air, where an enzyme then convert amino acids into lachrymator compounds, a form of sulfuric acid that can irritate the nerves around the eyes, causing tears.
The clothes we wear benefit from chemical advancements. Some chemicals used in clothing designed to prevent the penetration of bacteria or dirt into the fibers, thereby facilitating their removal during washing; other chemicals incorporated into the fibers create a ‘lubricating’ effect, potentially resulting in a softer fabric with reduced friction. Washing clothes, too, relies on chemical principles.
To perform as detergents (surface-active agents), soaps and detergents likely must contain molecules with a hydrophobic (water-insoluble) component, such as a fatty acid, or a long carbon chain group like those found in fatty alcohols or alkylbenzene. When washing hands with soap and water, the hydrophobic tails of the soap molecules attempt to evade water, potentially wedge themselves into the lipid envelopes of some microbes and viruses and prying them apart.
Food Science
Chemistry plays a central role in the history of food production, storage, and consumption, from preservation techniques and quality testing to the use of pesticides, artificial additives, and substitutes; even the art of cooking, which transforms ingredients and their combinations to create new textures and tastes, may be considered a chemical process.
The use of heat, cold, and cutting in any cooking process involves chemistry, as these actions can change the composition of foods; even simply slicing an apple sets off chemical reactions that alter the color of its flesh, much like heating sugar to turn it into syrup involves a chemical reaction.
Preservatives, both natural and synthetic, rely on chemical reactions to inhibit microbial growth. In food production and preservation, chemical substances play a significant role; some food additives, for example, can prolong the shelf life of foods, while others, such as colours, can enhance the visual appeal of food, and flavourings are employed to make food more palatable.
Among the commonly used artificial sweeteners approved by the WHO/FAO for inclusion in foods are acesulfame potassium, aspartame, saccharin, sucralose, cyclamate, and neotame, each of which is believed to have its own acceptable daily intake, unique metabolic properties, and potential impact on gut microbiota.
Preservatives, which can be composed of either natural or synthetic chemicals, include naturally occurring substances like salt, alcohol, or sugar; conversely, some common artificial preservatives used in food processing include sodium benzoate, sorbic acid, butylated hydroxyanisole (BHA), and butylated hydroxytoluene (BHT).
Even baking involves intricate chemical transformations. When baking powder is mixed with flour and subsequently water is added to form dough, the baking powder is undergo a chemical reaction that produces carbon dioxide gas; this gas, trapped within the dough, bubbles out, which contribute to the rising of the cake and its resulting soft, spongy texture.
The simple observation of ice floating in water highlights the unique chemical properties of water. Ice typically floats in water because its density is lower than that of liquid water, a phenomenon possibly attributed to the crystalline structure formed by frozen water molecules, which occupy more space; however, it’s worth noting that ice might not exhibit the same buoyant behavior in other fluids, such as air or alcohol.
Chemistry in Construction, Energy, and Agriculture
Chemistry plays a significant role in building and construction, potentially contribute to the creation of stronger, more durable materials; for instance, engineers often use chemical additives to enhance the properties of concrete for various projects, and protective coatings are employed to prevent steel from rusting.
The development of new materials, from stronger concrete to corrosion-resistant coatings, depends on chemical research. Our understanding of energy also relies on chemical principles. Chemistry contribute to our understanding of the properties of various fuels and potentially aid in optimizing their production, combustion processes, and overall environmental impact.
Batteries are thought to utilize chemical principles, specifically in the form of chemical potential, to store energy, much like many other common energy sources; for example, both logs and oxygen appear to store energy within their chemical bonds until combustion converts a portion of that chemical energy into heat.
In agriculture, chemistry plays a crucial role in crop protection and fertilization. Agricultural chemistry is employed in the production of pesticides and insecticides, which are widely used to protect crops from various external organisms; this includes the use of rodenticides, pediculicides, biocides, fungicides, herbicides, and other similar substances.
Chemistry and Engineering
Engineering disciplines, too, rely heavily on chemical knowledge. Engineering chemistry assist students in fields like Electronics & Telecommunications and Electrical Engineering in understanding the properties of conductors, semiconductors, sensors, and insulators; furthermore, knowledge of chemistry is also crucial in the fabrication of electronic devices, particularly for selecting appropriate materials to manipulate electron behavior.
The design and fabrication of electronic components depend on understanding the chemical properties of materials. The principles of green chemistry guide the development of sustainable chemical processes. Green chemistry aims to reduce pollution at its source by minimizing or eliminating the hazards associated with chemical feedstocks, reagents, solvents, and products.
The textile industry utilizes chemistry to develop new fibers and improve textile processing. Chemistry appears crucial for emerging cellulosic textile and nonwoven applications, potentially contributing to the creation of desirable properties in cellulosic textile fibers and enabling efficient production processes that offer water and energy savings; it is also to play a role in cotton waste and textile recycling processes.
In essence, chemistry underpins countless aspects of modern life. Chemistry plays a significant role in numerable aspects of daily life, arguably including medicines, cosmetics, soaps and detergents, textiles, building and construction, fuel, batteries, the chemical composition of an onion, baking, and food preservation.
Chemistry is arguably involved in numerous daily tasks, from seemingly simple activities like consuming safe foods and boiling water to eliminate bacteria, to using antibacterial soap; these everyday applications of chemistry often go unnoticed.
From the food we eat to the clothes we wear, from the medicines that heal us to the materials that build our homes, chemistry plays an essential, albeit often unseen, role. The importance of chemistry in everyday lifeit is integral to food, nutrition, preservation, clothing, medicines, and cosmetics, as engineers use materials for homes, vehicles, and fuels, which enhances farming with healthier crops while mitigating pollution.
